Document Type and Number:
WIPO Patent Application WO/2021/082347
Kind Code:
A1
Abstract:
Provided is a method for preparing a high-performance lithium-containing organic sulfur electrode material and an integrated flexible electrode. The present invention uses a method of using 1,3-diisopropenylbenzene having a diolefin bond and Li2S6 as precursors and using in-situ polymerization so as to carry out reaction and produce a lithium-containing organic sulfide Poly(Li2S6-r-DIB). As the synthesized lithium-containing organic sulfide Poly(Li2S6-r-DIB) shows good viscosity when heated to a certain temperature, same may be directly attached to a flexible conductive carbon cloth to thereby produce an integrated flexible electrode. The obtained flexible electrode has the advantages of having high capacity, high flexibility, a stable structure and so on.
